Cambridge SU is a democratic charity: almost all decisions are made by student representatives at SU Council. However, decisions regarding the legality of the students’ union’s actions, staffing matters, and many financial matters are ultimately overseen and enacted by the Board of Trustees.

Trustees are the guardians of the union’s assets and they are under a legal duty to act in the best interests of the charity, which involves making balanced and informed decisions about what will best enable the charity to carry out its purposes on behalf of its beneficiaries, the students of the University of Cambridge. Trustees must implement realistic and reasonable risk management strategies and processes to identify and mitigate risks to the charity’s funds and assets.

The Trustee Board, under the rules detailed in our Articles of Association, consists of: 

  • The five elected sabbatical officers
  • Up to three student member trustees
  • Up to four external trustees

Further information can be found in the SU's Governance Policies & Procedures
